Not that this applies to most of the folks here, but it does apply to me. From CAPT's MBTI Code of Ethics:
The information is not to be used to label, evaluate, or limit any individual in any way.
The administrator should be careful not to over generalize or over simplify results and imply that all people of a certain type behave the same way.
One should not state or imply that type explains everything.
Type does not reflect an individual's ability, intelligence, likelihood of success, emotions, or normalcy. Type is one important component of the complex human personality.
